第506行文件/var/www/html/projects/api/vendor.../src/Illuminate/Database/..HasRelationships.php中找不到模型类

Question

所有我的apis在localhost工作正常，我把它放在实时服务器（ubuntu 16.04）我收到此错误当我请求GET获取项目的特定细节我收到此错误。

Symfony\Component\Debug\Exception\FatalThrowableError: Class 'App\Rewards' not found in file /var/www/html/projectsfundingandsharing/api/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Concerns/HasRelationships.php on line 506
Stack trace:
  1. Symfony\Component\Debug\Exception\FatalThrowableError->() /var/www/html/projectsfundingandsharing/api/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Concerns/HasRelationships.php:506

为了得到特定的项目，我有很多班级模型（我使用了laravel雄辩的技术）

这是我的routes / api.php文件

use Illuminate\Http\Request;

Use App\Article;
Use App\Projects;
Use App\User;
Use App\Rewards;
Use App\Comments;
Use App\User_address;
Use App\Shipping_location;
Use App\ProjectController;
Use App\rewardsController;
Use App\storyController;
Use App\CommentsController;
use App\ActivationService;

//everything works fine when i call this api.
Route::get('projects', 'ProjectController@index');

//errors is occurring here when i trying get all relational models class.
Route::get('projects/{id}', function($id) {
   $project = Projects::with('rewardsProject.shippings','projectImage', 'projectFaqs','projectStory','userdetails', 'user.user_address')
          ->where('id', $id)
         ->get();
   return $project;
    //return Projects::find($id)->user->user_address; 
});

这是我的项目模型类

namespace App;
use App\Project_images;
use App\Comments;
use App\Rewards;
use Illuminate\Database\Eloquent\Model;
use Eloquent;
use Illuminate\Support\Facades\DB;
class Projects extends Model
{
   protected $fillable = ['title', 'video_url', 'pledged_amount', 'currency', 'end_date', 'funded_amount', 'percent_funded', 'funding_model', 'start_date', 'duration', 'category_id', 'category_name', 'user_name','user_id', 'total_backers', 'picture', 'links'];


   public function projectUser(){
    return $this->hasOne('App\User');
   }


   public function projectStory(){
    return $this->hasOne('App\Story');
   }
   public function projectFaqs(){
    return $this->hasMany('App\Faqs');
   }

   public function projectRewd()
   {
       return $this->belongsToMany('App\Rewards','rewards', 'projects_id');
       // return $this->hasMany('App\Rewards');

   }

   public function projectShip()
   {
       return $this->belongsToMany('App\Shipping_location', 'shipping_locations','reward_id','project_id');
       //return $this->belongsToMany('App\Role', 'role_user', 'user_id', 'role_id');
   }

   public function projectImage()
   {  
        return $this->hasMany('App\Project_images');
   }


    public function rewardsProject(){
        return $this->hasMany('App\Rewards');
    }
    public function userdetails(){
        return $this->hasOne('App\User','id', 'user_id');
    }
    public function user(){
        return $this->belongsTo('App\User');
        //return $this->hasManyThrough('App\User', 'App\User_address');
    }
}

这是我的rewards.php模型类

namespace App;

use Illuminate\Database\Eloquent\Model;

class rewards extends Model
{

    protected $fillable = ['amount', 'delivery_date', 'projects_id', 'quantity', 'backers_count', 'currency', 'contain_shipping_locations', 'title', 'description'];

   /*----*/
   public function projects() {
        return $this->belongsTo('App\Projects');
    }

    public function shippings(){
        return $this->belongsToMany('App\Shipping_location','rewards_shipping_location', 'reward_id', 'shipping_location_id');
    }




}

就像这样，我把所有正确的模型类。

请帮助我为什么我得到这个错误，我把App\Rewards路径放在所有类文件中，当我删除路由/ api.php文件中的rewardsProject.shippings我得到App/Story not found

Answer 1

你的班级没有命名为App\Rewards，你把它命名为App\rewards。

Linux区分大小写。自动装带器根据类名查找文件。自动加载器现在正在寻找Rewards.php而不是rewards.php。它不能自动加载你的课程。

在引用类时始终使用正确的大小写，即使PHP不关心，自动装带器也必须加载文件，文件系统可以区分大小写。总是假装区分大小写是一个问题。
